Historical Flood Alert Messages for this Area


Flood Alert issued on 23 Mar 2019 20:36
The Wash
Saturday evening's high tide (at 19:45) has now passed and water levels along the East Coast are returning to normal along the tidal River Witham and the Haven in Boston. The high tide levels may have resulted in seepage and water coming through manhole covers or unsecured flap valves causing localised pooling of water behind the defences. Low lying coastal land and roads may have been affected. If water levels are high please continue to avoid using low lying coastal footpaths near beaches or promenades and plan driving routes to avoid low lying roads, as sea spray and waves could be dangerous.


Flood Alert issued on 23 Mar 2019 08:44
The Wash
High tides are forecast, resulting in elevated water levels along the East Coast of England on Saturday evening. This will lead to unusually high water levels along the tidal River Witham and the Haven in Boston. The time and date of the forecast high water is 19:45 on 23 March 2019, however conditions may apply two to four hours either side of the high tide. The high tide levels may result in seepage and water coming through manhole covers or unsecured flap valves causing localised pooling of water behind the defences. We are not expecting the situation to escalate and therefore do not envisage issuing any subsequent flood warnings. Low lying coastal land and roads will be affected first. Please avoid using low lying coastal footpaths near beaches or promenades and plan driving routes to avoid low lying roads, as sea spray and waves could be dangerous.

Stormy conditions are forecast, resulting in a large tidal surge moving down the East Coast of England on Thursday evening. This will lead to unusually high tidal levels along tidal River Witham and the Wash frontage. The time and date of the forecast high water is 18:42 on 1 Feb 2018. The high tides combined with strong winds may result in wind-blown spray and wave splash causing localised pooling of water behind the sea defences. The forecast high water level is 5.06 metres AOD (8.85m Boston Sill level or 7.93m chart datum). Precautionary flood warning for waterside properties between Town Bridge and Haven Bridge in Boston is in place. Low lying coastal land and roads will be affected first. Be careful along beaches, promenades, coastal footpaths and roads as sea spray and waves could be dangerous.
